MP215 Mobile Modem

Installation, Configuration, and User’s Guide

If the cable loss between the modem and antenna is greater then 2 dB, it is acceptable to use a 3 dB gain antenna as the ERP will be within the 36 dBm +2/-4 dB limit. 2dB loss results when using approximately 15 feet or RG-58 co-axial cable.

The antenna should be mounted well away from any objects that may ‘shield’ it from receiving signals. A roof top location is best. The antenna location may be adjusted based on experimentation, using the RSSI reading displayed by the Watcher application.
